To paint your display cabinet, start by removing any hardware and cleaning the surface thoroughly. Sand the cabinet to create a smooth surface for the paint to adhere to. Apply a primer to the cabinet to ensure better adhesion and coverage of the paint. Once the primer is dry, apply your chosen paint color in thin, even coats, allowing each coat to dry completely before applying the next. Finally, reattach the hardware and let the paint cure for the recommended time before using the cabinet. **

Mercury is a toxic substance, so it is important to handle it with caution and follow proper safety protocols when dealing with it. **
